Keeping track of business expenses can be a huge pain in the buttocks, but webapp Xpenser is out to make it as easy as a phonecall, SMS, or instant message. Back when we first mentioned Xpenser it used the then-free Jott voice transcription service; today it now also works with the free, international voice service Dial2Do so you can call in an expense, like "Lunch 34 with Jack." Xpenser's latest update also offers multiple tags per expense, so you can add keywords like "travel," "amex," and a particular client's name. For folks who spend a lot of business-related money on the road, Xpenser looks like one of the easiest ways to avoid the dreaded stack of crumpled receipts come tax time.
